A useful agent now has to build the harness that proves its answer can survive contact with the world.

• The Verification Pass

Once the trace becomes material for the next run, observability stops being a dashboard and becomes part of the agent's workspace.

• The Token Budget Becomes Power

Once an agent can read the inbox, move the calendar, and leave an audit trail, the product boundary moves to the place where work already has consequences.

• The Work Surface Becomes the Interface
